I entered “alphabet”, “numbers”, and “multibyte characters such as Japanese” into Text SOP.
In the 3D preview, only the multibyte characters are displayed in dark gray.
This happens in the operator preview and in the geometry viewer.
This phenomenon occurs on macOS.
It does not seem to occur in indows.
